NEW YORK (Reuters Health) - Contrary to earlier reports, everyday exposure to phthalates -- chemical plasticizers used extensively in household products and in certain medical products -- may not have harmful effects on fertility in young men, a new study shows.Previous studies suggested that low levels of phthalate exposure could adversely affect human semen, the authors explain in a report in Epidemiology, a medical journal, but high doses of phthalates are required to provoke male reproductive toxicity in rats.
